That looks like a bug. I wonder why none of my compilers complained? What compiler version are you using?
$ gcc -v

Hmm, maybe it's an issue with one of your compiler flags. Anyway, it certainly is a bug with the code, which will be fixed shortly.
Move global variable definition from header into source file (Closed by 1d444e4)
Looks like the issue was you had the -fno-common option enabled:
In C, allocate even uninitialized global variables in
the data section of the object file, rather than
generating them as common blocks. This has the effect
that if the same variable is declared (without
`extern') in two different compilations, you will get
an error when you link them. The only reason this
might be useful is if you wish to verify that the
program will work on other systems which always work
this way.
I have this same problem building 0.9.1 in Snow Leopard, Ruby 1.9.2-p0. Some info:

I can confirm that this is fixed when building from the master branch. Thanks.
